The date above is the publisher’s own but not yet final, so it carries an EST. tag until it is confirmed.

Honkai: Star Rail Version 4.5: To Roll the Stars in Astropolis is estimated to end around September 29, 2026 (verified September 3, 2026). Version 4.5: To Roll the Stars in Astropolis takes the Astral Express crew to a seaside city for a summer story arc, and it is deliberately short: HoYoverse announced a five-week run instead of the usual six. Its two banner phases debut Robin • Summeretto, a Wind Remembrance unit, and Aventurine • Waveflair, a Quantum Elation unit, with Hyacine and Ashveil reruns alongside. The end date becomes official only when the 4.6 maintenance notice is posted, typically a day or two ahead, so until then the countdown above follows the shortened schedule. The Nameless Honor pass costs $9.99 for Nameless Glory or $19.99 for Nameless Medal, and a free track is open to everyone.
Honkai: Star Rail Version 4.5: "To Roll the Stars in Astropolis" launched August 26, 2026, sending the Astral Express crew to the seaside city of Astropolis for a summer-themed story arc. HoYoverse has confirmed this version runs five weeks instead of the usual six, so it is estimated to end around September 29, 2026, when Version 4.6 maintenance is expected to begin. That date is only firm once HoYoverse posts the 4.6 notice.
The update debuts two new 5-star units — Robin • Summeretto (Remembrance, Wind) and Aventurine • Waveflair (Elation, Quantum) — with second-half banners arriving September 12, 2026.
Recent versions have run close to but not exactly on a 42-day cycle: Version 4.4: In Ravages Does the Whistle Sound (July 14 – August 25, 2026, 42 days), Version 4.3: The Lethe Below the Living (May 31 – July 14, 2026, 44 days), Version 4.2: So Laughed the Masses (April 21 – May 31, 2026, 40 days), and Version 4.1: Unraveled for Daybreak (March 24 – April 21, 2026, a shorter 28-day cycle).
The cadence carries some jitter rather than landing on a strict 42 days every time, and this run is a deliberately shorter five-week cycle, which is why the end date is only firm once HoYoverse announces the next version.
The seasonal Nameless Honor battle pass costs $9.99 for the Nameless Glory tier or $19.99 for the higher Nameless Medal tier, both covering the full run of Version 4.5. A free track is available to all players.
